Aneutral kaon decays into two pions via the process k0 → π+π-where mk0-500 mev/c2 and the pion masses are both 140 mev/c. if the kaon is at rest, what are the energies (in mev), momenta (in mev/c), and velocities (in units of c) of the pions 7. refer to the previous problem. if the kaon moves in the lab with a kinetic energy of 600 mev, and the positive pion is emitted along the kaon's direction of motion, find the kinetic energies (in mev) and momenta (in mev/c) of each pion. 8. refer to the previous problem. the kaon has the same lab kinetic energy as in the previous problem, but the positive pion is emitted 45° relative to the kaon's direction of motion (measured in the kaon's rest frame). use conservation of energy and momentum to find the kinetic energies in mev), momenta (in mev/c) and angles (in degrees) of each pion relative to the kaon initial direction
